METHOD AND DEVICE FOR THE SEISMIC EVALUATION OF A GEOLOGICAL FORMATION

摘要

The invention relates to a method for seismic evaluation, in particular of the vicinity of a bore (1) in a geological formation (2). Said method comprises the following steps: provision of a source system (10) comprising at least two seismic sources (11) in the bore (1); generation of seismic waves that propagate in the geological formation (2) with predefined emission characteristics formed by the two or more seismic sources (11); and recording of the seismic waves using a recording system (20). The invention also discloses a seismic system (100) for seismic evaluation of the vicinity of a bore in a geological formation, comprising a source system (10) with at least two seismic sources (11), said source system having predefined emission characteristics and being positionable in the bore (1), and comprising a recording system (20) that can record seismic waves in the vicinity of the bore (1).
